I have been given a 95 SL1, and have just started fixing things a bit. I have noticed that it puts out a _lot_ of soot. I've read the earlier posts and arguments about soot in the tailpipe, but this is not even close to that. If I start the engine, and idle for, say, 15 seconds, then go to the back of the car, the ground below the tailpipe is black. If I put my hand under the tailpipe, it quickly gets coated with soot. Does anyone have any suggestions as to what might be causing this?
Other things on this car that might be relevant: - diagnostics says the egr system has a fault (probably bad egr valve?) - diagnostics sometimes says that o2 sensor claims engine is running rich - consumes enormous amounts of oil (1qt every 100-200 miles -- so like every few days) - smells terrible, and puts out a lot of smoke.
Any help is greatly appreciated!
